How to detect that a Data Flow Task has failed (from inside a custom componet)

SSIS 2005 Control Flow Task Priority

The short version is I am looking for a way to prioritize certain tasks in SSIS 2005 control flows. That is I want to be able to set it up so that Task B does not start until Task A has started but Task B does not need to wait for Task A to complete. The goal is to reduce the amount of time where I have idle threads hanging around waiting for Task A to complete so that they can move onto Tasks C, D & E. The issue I am dealing with is converting a data warehouse load from a linear job that calls a bunch of SPs to an SSIS package calling the same SPs but running multiple threads in parallel. So basically I have a bunch of Execute SQL Task and Sequence Container objects with Precedent Constraints mapping out the dependencies. So far no problems, things are working and initial testing looks like it will cut our load time significantly. However I noticed that tasks with no downstream dependencies are commonly being sequenced before those that do have dependencies. This is causing a lot of idle time in certain spots that I would like to minimize. For example: I have about 60 procs involved with this load, ~10 of them have no dependencies at all and can run at any time. Then I have another one with no upstream dependencies but almost every other task in the job is dependent on it. I would like to make sure that the task with the dependencies is running before I pick up any of t

Data Flow Task failing to drag-and-drop onto SSIS Control Flow

This morning, I started having problems with Visual Studio 2005 on XP when I tried to create an SSIS project; I was getting an error message about the failure to create an SSIS runtime object, with the reference "Unable to cast COM of type 'Microsoft.SqlServer.DTS.Runtime.Wrapper.PackageNeutralClass' to interface type". Digging here and elsewhere on the Net, I used regsvr32 to re-register msxml3.dll, msxml6.dll, and dts.dll. This allowed me to create a new SSIS project, but I was unable to add a data flow task to the Control Flow pane -- when I dragged the control onto the pane, nothing happened, and when opened the Data Flow pane and clicked on the 'No data flow task has been defined. Click here to create a data flow task" link, I got a 'Failed to create the task. The designer could not be initialized." error. Searching here and on the Net, I uninstalled and reinstalled the SQL Server 2005 workstation tools.

After doing this, I am still unable to create a data flow task by dragging the task out of the toolbox; the pointer assumes the right form for the drag-and-drop, as it does for other tasks, but when I release the mouse button, nothing happens. However, when I go to the Data Flow pane and click on the 'click here to create a new data flow task', it creates the task, and I am able to use copy-and-paste to make copies of the data flow task

Delimiter File Read Task Installer failed to show in SSIS Data Flow Items


I downloaded the Delimiter File Read and followed the instruction and installed it. The file is on the correct directory (>:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents) The file DelimitedFileReader.dll is there.

However, when I go to BI Development Studio and try to add the new task I can't see it in the SSIS Data Flow Items...it is not visible. Does anyone know why I can add/see it?



Unable to create task using Custom task Process Action in Sharepoint Designer 2010 workflow

Problem : In Sharepoint Designer 2010, we are working on creating reusable workflow.
In workflow we are using "Start Custom task process" action. It has been observed that,all of the sudden it behaves weirdly. It creates task but without any number appending to taskform.for eg. when we create task it generally shows "Start Task(1) process on Current Item with these users" However now it does not provide any number with Task. It shows "Start Task process on Current Item with These users"
In task form , it does not allows to add task forms fields from existing fields nor allows to create outcomes.
Thus we are unable to create any new workflows or edit and enhance exisitng workflows in the site.This is showstoper for project. Client wants to use sharepoint designer exclusively to develop workflow.
When we tried to create workflow (Sharepoint designer) in a new site with new list it allows us to create custom tasks process. 
Resoultions approaches done so far.
1) Took backup of site on local box from Server and tried to create custom process task but not able to do it.
2) On Server removed all unwanted workflow status columns from the tasks list but still not able to create custom process task 
3) Took backup and t

Can I create several steps to be run on a SharePoint list as a task to run on a daily basis?


We have a manual process that we do on a SharePoint list to export data from SharePoint to a spreadsheet that can then be used by non SharePoint programs.  I'd like to be able to automate this process so that it can be scheduled as a Task to run on a daily basis.   Not sure if a workflow can do what I'd like it to.  I have SharePoint Designer 2007 as well.

Here are the steps:

1. Load a particular View of a SharePoint List

2. From the view's Action menu, "Open with Access"

3. Save the resulting Access database as a file to a specific Folder on the computer hosting SharePoint

This would be run as a Task on the computer hosting SharePoint.

How do I add two XML tasks to a Data FLow task?

I am new to SSIS and am developing a package which takes input from an XML file and then populates an existing SQL table with these records.  However, this is a very large XML file.  I keep getting an Out of Memory exception.  (This file is 210 MB)!  So what I tried doing was separating this XML file into 8 smaller files.  Now, I can successfully load data from these smaller files one at a time.  But how can I do all of them in the same package?  I connected two XML tasks to the Data Flow task and get the error below.  I also increased my timeout and number of errors to no avail.  Advice? Error: 0xC002F304 at XML Task 1, XML Task: An error occurred with the following error message: "Exception of type 'System.OutOfMemoryException' was thrown.". Task failed: XML Task 1 Warning: 0x80019002 at zSkywardEnrollment: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

Data flow task with multiple destinations randomly hangs

I have a package whose control flow consisting of a single data flow task with multiple destinations continues to hang at random locations.  The data flow task is fairly simple: - One OLE DB source (one query of selecting about 10 fields from one table) - 9 lookups that serve basically as left joins to capture which data "drops off" (does a row redirect on on lookup errors to an "error flow") - Two destinations: one the captures all the data that doesn't drop off from the lookups, and another to capture the data that does drop off; these write to two tables unrelated to each other, and unrelated to any of the tables I'm reading from I have tried the following: - Changed one or both destinations from OLE DB to flat file -- still randomly hangs - Removed both destinations altogether -- this always suceeds.   - Removed destination A and leave destination B -- this always succeeds - Removed destination B and leave destination A -- this always succeeds I took great care in making sure I get no warnings when the package runs, even resolving the unneeded column warnings, and the duplicate keys on all my lookups, but it still hangs. However, once I give up and stop the package, the following error is thrown (among others that appear to be a byproduct of the root issue): Error: 0xC02020C4 at Data Flow Task, OLE_SRC AP12 [1]: The attempt to
